SciShow explains the differences between ‘Zero G’ and ‘Zero Gravity’

SciShow (previously) host Hank Green explains the differences between the concepts of “zero g” and “zero gravity.” It’s an important distinction, so far as the basic workings of the Universe are concerned.

Zero G does not truly mean zero gravity, because there is gravity everywhere. If there were truly no gravity, plants and stars wouldn’t even form, let alone orbit around each other.
